a C++ compiler named 'c++', and a Fortran compiler named 'g77' (such
as found in the GNU C compiler suite) on any other type of system.

SCons compatibility package for old Python versions
This subpackage holds modules that provide backwards-compatible
implementations of various things that we'd like to use in SCons but which
only show up in later versions of Python than the early, old version(s)
we still support.
Other code will not generally reference things in this package through
the SCons.compat namespace. The modules included here add things to
the builtins namespace or the global module list so that the rest
of our code can use the objects and names imported here regardless of
Python version.
The rest of the things here will be in individual compatibility modules
that are either: 1) suitably modified copies of the future modules that
we want to use; or 2) backwards compatible re-implementations of the
specific portions of a future module's API that we want to use.
GENERAL WARNINGS: Implementations of functions in the SCons.compat
modules are *NOT* guaranteed to be fully compliant with these functions in
later versions of Python. We are only concerned with adding functionality
that we actually use in SCons, so be wary if you lift this code for
other uses. (That said, making these more nearly the same as later,
official versions is still a desirable goal, we just don't need to be
obsessive about it.)
We name the compatibility modules with an initial '_scons_' (for example,
_scons_subprocess.py is our compatibility module for subprocess) so
that we can still try to import the real module name and fall back to
our compatibility module if we get an ImportError. The import_as()
function defined below loads the module as the "real" name (without the
'_scons'), after which all of the "import {module}" statements in the
rest of our code will find our pre-loaded compatibility module.

"""Dependency scanner for Python code.
One important note about the design is that this does not take any dependencies
upon packages or binaries in the Python installation unless they are listed in
PYTHONPATH. To do otherwise would have required code to determine where the
Python installation is, which is outside of the scope of a scanner like this.
If consumers want to pick up dependencies upon these packages, they must put
those directories in PYTHONPATH.

""" Re-parse the leftover command-line options.
Parse options stored in `self.largs`, so that any value
overridden on the command line is immediately available
if the user turns around and does a :func:`GetOption` right away.
We mimic the processing of the single args
in the original OptionParser._process_args(), but here we
allow exact matches for long-opts only (no partial
argument names!).
Else, this would lead to problems in add_local_option()
in the original OptionParser :func:`_process_args`, but here we
allow exact matches for long-opts only (no partial argument names!).
Otherwise there could be problems in :func:`add_local_option`
below. When called from there, we try to reparse the
command-line arguments that
1. haven't been processed so far (self.largs), but
1. haven't been processed so far (`self.largs`), but
2. are possibly not added to the list of options yet.
So, when we only have a value for "--myargument" yet,
a command-line argument of "--myarg=test" would set it.
Responsible for this behaviour is the method
_match_long_opt(), which allows for partial matches of
the option name, as long as the common prefix appears to
be unique.
So, when we only have a value for "--myargument" so far,
a command-line argument of "--myarg=test" would set it,
per the behaviour of :func:`_match_long_opt`,
which allows for partial matches of the option name,
as long as the common prefix appears to be unique.
This would lead to further confusion, because we might want
to add another option "--myarg" later on (see issue #2929).

This is the flow of the compiler detection logic:
External to MSCommon:
The Tool init modules, in their exists() routines, call -> msvc_exists(env)
At the moment, those modules are:
SCons/Tool/midl.py
SCons/Tool/mslib.py
SCons/Tool/mslink.py
SCons/Tool/msvc.py
SCons/Tool/msvs.py
env may contain a version request in MSVC_VERSION, but this is not used
in the detection that follows from msvc_exists(), only in the later
batch that starts with a call to msvc_setup_env().
Internal to MSCommon/vc.py:
+ MSCommon/vc.py:msvc_exists:
| vcs = cached_get_installed_vcs(env)
| returns True if vcs > 0
|
+-> MSCommon/vc.py:cached_get_installed_vcs:
| checks global if we've run previously, if so return it
| populate the global from -> get_installed_vcs(env)
|
+-> MSCommon/vc.py:get_installed_vcs:
| loop through "known" versions of msvc, granularity is maj.min
| check for product dir -> find_vc_pdir(env, ver)
|
+-> MSCommon/vc.py:find_vc_pdir:
| From the msvc-version to pdir mapping dict, get reg key base and value
| If value is none -> find_vc_pdir_vswhere(ver, env)
|
+-> MSCommon/vc.py:find_vc_pdir_vswhere:
| From the vc-version to VS-version mapping table get string
| Figure out where vswhere is -> msvc_find_vswhere()
| Use subprocess to call vswhere, return first line of match
/
| else get product directory from registry (<= 14.0)
/
| if we found one -> _check_cl_exists_in_vc_dir(env, pdir, ver)
|
+-> MSCommon/vc.py:_check_cl_exists_in_vc_dir:
| Figure out host/target pair
| if version > 14.0 get specific version by looking in
| pdir + Auxiliary/Build/Microsoft/VCToolsVersion/default.txt
| look for pdir + Tools/MSVC/{specver}/bin/host/target/cl.exe
| if 14.0 or less, "do older stuff"
All of this just got us a yes-no answer on whether /some/ msvc version
exists, but does populate __INSTALLED_VCS_RUN with all of the top-level
versions as noted for get_installed_vcs
Externally:
Once a module's exists() has been called (or, in the case of
clang/clangxx, after the compiler has been detected by other means -
those still expect the rest of the msvc chain but not cl.exe)
the module's generate() function calls -> msvc_setup_env_once(env)
Internally:
+ MSCommon/vc.py:msvc_setup_env_once:
| checks for environment flag MSVC_SETUP_RUN
| if not, -> msvc_setup_env(env) and set flag
|
+-+ MSCommon/vc.py:msvc_setup_env:
| set ver from -> get_default_version(env)
|
+-+ MSCommon/vc.py:get_default_version:
| if no version specified in env.MSVC_VERSION:
| return first entry from -> cached_get_installed_vcs(env)
| else return requested version
/
| get script from MSVC_USE_SCRIPT if set to a filename
| -> script_env(script)
|
+-+ MSCommon/vc.py:script_env:
| return (possibly cached) script variables matching script arg
/
| else -> msvc_find_valid_batch_script(env, version)
|
+-+ MSCommon/vc.py:msvc_find_valid_batch_script:
| Build a list of plausible target values, and loop through
| look for host + target -> find_batch_file(env, ver, host, target)
|
+-+ MSCommon/vc.py:find_batch_file:
| call -> find_vc_pdir (see above)
| use the return to construct a version-biased batfile path, check
/
| if not found, try sdk scripts (unknown if this is still useful)
Problems:
- For VS >= 2017, VS and VS are not 1:1, there can be many VC for one VS
- For vswhere-ready versions, detection does not proceed beyond the
product level ("2019") into individual "features" (individual msvc)
- As documented for MSVC_VERSION, compilers can only be requested if versions
are from the set in _VCVER, so 14.1 but not 14.16 or 14.16.27023
- Information found in the first pass (msvs_exists) isn't really
available anywhere except the cached version list, since we just
return true/false.
- Since msvc_exists chain of calls does not look at version, we
can proceed to compiler setup if *any* msvc was found, even if the
one requested wasn't found.

"""SCons.Tool
SCons tool selection.
This looks for modules that define a callable object that can modify
a construction environment as appropriate for a given tool (or tool
chain).
Note that because this subsystem just *selects* a callable that can
modify a construction environment, it's possible for people to define
their own "tool specification" in an arbitrary callable function. No
one needs to use or tie in to this subsystem in order to roll their own
tool specifications.

Implements the ability for SCons to emit a compilation database for the MongoDB project. See
http://clang.llvm.org/docs/JSONCompilationDatabase.html for details on what a compilation
database is, and why you might want one. The only user visible entry point here is
'env.CompilationDatabase'. This method takes an optional 'target' to name the file that
should hold the compilation database, otherwise, the file defaults to compile_commands.json,
which is the name that most clang tools search for by default.
